The working end of pincers, nippers or tongs. The shape and size depends on the type of work being performed with the tool.

The point of contact between two or more bones. Joints are classified according to structure and function. Structural classification is determined by how the bones connect to each other. The most obvious  are  synovial joints, where the bone ends are not directly joined but are held together by a capsule filled with viscous fluid. These joints are capable of a wide range of movement. Fibrous joints are joined by dense fibrous connective tissue and practically imobile for example the fibrous joints between the skull bones. In cartilaginous joints, the ends of the bone are joined by a 'bridge' of cartilage, allowing a small degree of movement, for example the joints between the body of the vertebrae. 

A capsule made of fibrous connective tissue that is firmly attached to the periosteum of the bone at the edge of the joint cartilage. The joint capsule completely envelopes the joint and is lined by a membrane (synovial membane) which secretes the viscousjoint fluid (synovial fluid).

The groove running the length of the ventral side of the neck between the M. brachiocephalicus and the M. sternocephalicus. The jugular vein is located within the jugular groove, this is the preferred site of intravenous injection in the horse.
